Labour Won a Landslide With a Third of the Vote. That Should Trouble Everyone.

There is a number that ought to be repeated at every dinner party, every pub quiz and every hustings between now and the next general election: 33.7 per cent. That is the share of the vote that carried Labour to 411 seats in July 2024 — a working majority of 174, the largest since 1997, secured with the support of barely one voter in three.

Reboot Britain exists because we believe democracy should not work like this. And the 2024 result was not a quirk or a one-off. It was the logical endpoint of a system that has been breaking quietly for decades.

The Mathematics of Distortion

First past the post (FPTP) only makes sense if you imagine a two-party country. Britain stopped being that country sometime in the 1970s. In 2024, the two legacy parties combined for their lowest-ever joint vote share — around 57 per cent — yet walked away with more than 90 per cent of the seats.

The distortions ran in every direction. Reform UK won 14.3 per cent of the national vote and five seats. The Liberal Democrats won 12.2 per cent and 72 seats. The Greens, on 6.4 per cent, took four. Meanwhile the SNP, with 2.5 per cent of the UK vote, held 9 seats — while the SNP's Scottish collapse saw 63 per cent of their votes evaporate into 38 seat losses.

Consider the ratio of votes to seats. The Conservatives needed roughly 23,000 votes per seat won. Labour needed around 23,000 too, thanks to efficient vote distribution. Reform? Approximately 820,000 votes per seat. The Greens, over 1.5 million. This is not a system that treats votes equally. It is a lottery in which where you live matters more than what you believe.

What a Proportional Parliament Would Have Looked Like

Apply a straightforward proportional method — such as the mixed member system used for the Scottish Parliament and Welsh Senedd — to the 2024 results, and the picture changes dramatically.

Labour would still have been the largest party, but with roughly 226 seats rather than 411. The Conservatives would have taken around 190. Reform UK, on its actual vote share, would have held approximately 94 seats. The Liberal Democrats around 66, the Greens roughly 32, the SNP about 17, and Plaid Cymru a fairer handful reflecting its Welsh vote.

In other words: no landslide, no majority, and no government able to pass whatever it likes for five years on the say-so of a third of the electorate. Instead, a negotiated parliament — one where Reform supporters in Clacton and Green supporters in Bristol and Liberal Democrats in the Home Counties would all see their votes count for something.

Would that be worse for voters? The evidence suggests otherwise.

The Coalition Canard

The defenders of FPTP offer two arguments: that it delivers 'strong government', and that proportional systems empower fringe parties. Both deserve scrutiny.

'Strong government' is a curious euphemism for a system that allowed Boris Johnson to pass legislation with a 80-seat majority won on 43.6 per cent of the vote, or that delivered the Brexit referendum result and its aftermath with no parliamentary check on executive power. Strength without legitimacy is brittle. The 2022 mini-budget — a programme of unfunded tax cuts imposed by a government answerable to no coalition partner — was pure FPTP 'strength', and it wrecked mortgages and pensions within a fortnight.

As for fringe parties: they are already here. Reform won five seats under FPTP and dominates the airwaves. The difference under PR is that a party with 14 per cent support would have to persuade other parties to work with it, rather than simply hoping to capture a major party from within. Proportional systems do not remove extremes; they make them negotiate.

And coalition politics is not alien to Britain. Northern Ireland has used STV for a century. Scotland and Wales have run successfully on mixed systems since 1999. Voters in those nations have consistently declined to give them up. New Zealand switched to MMP in 1996; three decades on, no serious movement exists to return to the old system.

Why Nothing Changes — Yet

The honest answer to 'why haven't we reformed this?' is that the people with the power to change the system are the people it serves. Labour won 63 per cent of the seats on 34 per cent of the vote; the Conservatives before them did something similar in 2019. Neither has an incentive to volunteer for permanent coalition.

But the pressure is building. The 2024 election was the most disproportional in British history, and the one before it was hardly better. When 58 per cent of voters backed parties other than the two largest, and millions saw their ballots effectively count for nothing, the legitimacy question stops being academic.

Change will not come from Westminster's goodwill. It will come from voters demanding it — through campaigns like Make Votes Matter, through local parties adopting PR in their manifestos, through the slow accumulation of public frustration. A citizens' assembly on electoral reform, as we have argued elsewhere, would be an ideal first step: put the evidence in front of a representative sample of the British public and let them weigh it.

Democracy is supposed to be the system where the people choose their government. In Britain in 2024, the government chose itself — with the help of an electoral map that no longer resembles the country it claims to represent. That is not a reboot. That is a system running on borrowed legitimacy.

The question is not whether Britain can afford proportional representation. It is whether it can afford much more of this.
